What effect does nicotine have on muscle building?

Snus has been used for some time by athletes, especially ice hockey and football players, before important competitions. This suggests that nicotine influences muscle growth and leads to improved performance. We want to get to the bottom of this and explain what effect nicotine has on strength training and whether using Snus is really helpful for muscle building.

How does nicotine affect muscle growth?

First, it should be noted that the effect of nicotine strongly depends on the use of Snus, for example how often a person consumes Snus, the nicotine content, and how long the pouches are kept in the mouth. Individual factors also play a role, as every body reacts differently to nicotine.

The intake of nicotine has both positive and negative effects on muscle growth. But how does muscle growth actually work? Muscles develop when the load increases and the muscles adapt to the new stimuli during the recovery period. Due to the increased load, the cross-section of the muscle fibers enlarges and they become thicker.

What happens when nicotine is absorbed?

As soon as nicotine is absorbed by the body, blood flow in the muscles worsens and they receive less energy. As a result, the body cannot build muscle mass as usual, and strength performance decreases. Coordination of athletes also deteriorates because the transmission of signals between the muscles is disrupted.

So why are more and more athletes turning to nicotine, and how does performance enhancement through Snus happen? Nicotine triggers positive feelings in the body because the reward center is activated and more dopamine is released. At the same time, adrenaline levels rise, and athletes feel more energized. Negative feelings like nervousness and stress are suppressed, allowing better concentration.

Snus and metabolism

As already mentioned, nicotine intake increases the release of dopamine, adrenaline, and serotonin. It is well known that a sudden smoking cessation leads to weight gain, and the same can happen with other nicotine products because dopamine suppresses hunger. Thus, athletes gain weight faster when they stop using Snus or similar products.

Overview of Snus effects on muscle growth

Positive effects

• Increased concentration
• Nervousness is suppressed
• Adrenaline levels rise
• Dopamine release is increased

Negative effects

• Energy supply decreases
• Blood circulation worsens
• Coordination is disturbed
• Strength performance decreases

Snus and other nicotine products as doping agents?

Nicotine-containing products like Snus are currently only on the watchlist of the World Anti-Doping Agency and have not been banned in sports. Since studies have not yet proven a clear performance enhancement, nicotine is (still) not on the banned list. It is clear that Snus has a stimulating effect, but this alone is not enough to gain clear advantages in competitions.

Comparison of cigarettes and Snus in muscle growth

Occasionally, the media report that even professional athletes turn to cigarettes. This can have devastating effects on muscle growth because a cigarette leads to higher carbon monoxide intake, which accumulates in the lungs. Carbon monoxide binds to red blood cells and slows oxygen transport. Oxygen is needed during muscle growth to provide energy.

In contrast, Snus does not involve combustion during use, so athletes do not have to worry about carbon monoxide. Those who want to build muscle despite using Snus should reduce the nicotine content.

Conclusion

Nicotine-containing products like Snus have both positive and negative effects on muscle growth. Nicotine increases the production of adrenaline and dopamine, which is desirable in sports. However, it reduces energy supply and worsens blood circulation, two crucial factors that can slow muscle growth. Further studies are needed to make definitive statements about Snus and performance enhancement.
